mostly in bg's where i don't know raid members, if the one's that are not within healing range were somehow identified (ie: grayed out), my mouse will live much longer not having to target and try casting a heal and see "out of range". i target with my mouse and cast spells with keys so it would be nice if ctraid ( or whatever frame that does this) is where the effect happens. if there is a mode that does this to to the raid frames o blizz, ctraid, ect, or a raid frame mod that can do this, please link it
